Abstract
The invention discloses a method for preparing organic silicon diluent for drilling fluid. The method comprises the following steps of: adding an appropriate amount of water into a reaction kettle, adding methyl chlorosilane, fully reacting and cooling the reaction product; and adding cooled solution into alkali solution under the action of aluminum salt serving as a catalyst to react with stirring for 4 hours so as to form the organic silicon diluent for the drilling fluid. A viscosity breaking agent obtained by the method has the advantages of high temperature resistance, capability of resisting a high temperature of over 240 DEG C, high compatibility with other substances, good slurry rheological behavior, high high-temperature stability and high diluting, viscosity breaking and lubricating performance. The organic silicon content of the agent is more than or equal to 18 percent, the chloride content is less than or equal to 10 percent and the viscosity breaking rate at room temperature is more than or equal to 60 percent and more than or equal to 82 percent for 16 hours at the temperature of 220 DEG C.
